Traditional concerns about concentration in product markets have centered on the social loss associated with the mispricing that occurs when market power is exercised. This paper focuses on a potentially greater loss from market power—a reduction in cost efficiency brought about by the lack of market discipline in concentrated markets. We employ data from the commercial banking industry, which produces very homogeneous products in multiple markets with differing degrees of market concentration. We find the estimated efficiency cost of concentration to be several times larger than the social loss from mispricing as traditionally measured by the welfare triangle.

This paper investigates the usefulness of a dynamic analysis of audit‐market competition in terms of audit‐market‐share mobility, audit‐firm entry, and audit‐firm exit. These dynamic measures of market structure are compared between the more regulated German audit market and the more liberal Dutch audit market. Prior research on audit market structure has focused on static analyses in terms of seller concentration of single national audit markets. By using data on the number of auditors as the measure of audit‐firm size, this paper covers all firms active in the two audit markets in the period 1970 to 1994. The results indicate that the more liberal Dutch audit market has the highest dynamic measures of market structure and the highest concentration. Hence, the results show that high concentration can go hand in hand with high‐market‐share mobility and high audit‐firm entry and exit. The results for market‐share mobility also hold for an analysis including only the largest audit firms. The paper therefore concludes, that compared with a static seller concentration analysis, an analysis of audit‐market dynamics provides a better description of the degree of competition in audit markets.

The performance goal for a unit is commonly created by consolidating the goals of its subunits. This paper shows that if it is difficult (easy) for the subunits to achieve their goals, it is almost always even more difficult (easier) for the unit to whole will almost certainly not meet a goal to cut its costs by a certain percentage if the degree of cost cutting is difficult to achieve at the individual subunit levels.

[The performance goal for a unit is commonly created by consolidating the goals of its subunits. This paper shows that if it is difficult (easy) for the subunits to achieve their goals, it is almost always even more difficult (easier) for the unit to achieve the consolidated goal. This means, for example, that the firm as a whole will almost certainly not meet a goal to cut its costs by a certain percentage if the degree of cost cutting is difficult to achieve at the individual subunit levels.]

This study tests predictions that pricing multiples on and incremental explanatory power of equity book value (net income) increase (decrease) as financial health decreases. Tests using a sample of 396 bankrupt firms and tests using a larger, pooled sample both yield inferences consistent with predictions. Findings are robust to inclusion of controls for industry, size, return-on-equity, and volatility of equity returns. Equity book value and net income multiples and incremental explanatory power vary predictably across three illustrative industries, selected based on the likely extent of unrecognized intangible assets.

Eastern Airlines' bankruptcy illustrates the devastating effect on firm value of court-sponsored asset stripping, i.e., the use of creditors' collateral to invest in high-variance negative net present value projects. During its bankruptcy, Eastern's value dropped over 50%. A substantial portion of this value decline occurred because an overprotective court insulated Eastern from market forces and allowed value-destroying operations to continue long after it was clear that Eastern should have been shut down. The failure of Eastern's Chapter 11 demonstrates the importance of having a bankruptcy process that protects a distressed firm's assets, not simply from a run by creditors, but also from overly optimistic managers and misguided judges.

The paper is concerned with developing a production theory for the case when some inputs have nonlinear prices because the price depends on endogenous quality. This involves extending the notion of a cost function to the case where nonlinear prices are parameters of costs. After developing the appropriate theory, we apply our results to the case of coal-fired electric power generation where fuel quality depends on sulfur and ash impurities. Environmental regulations induce a negative value on sulfur whereas ash impurities degrade performance and thus reduce production possibilities. A number of empirical results emerge, including significant rates of technological change that are sulfur and ash saving though capital using. This change may explain in part the recent drop in the price of sulfur allowances in the United States.

This paper examines the effect of skill-biased technological change as measured by computerization on the recent widening of U. S. educational wage differentials. An analysis of aggregate changes in the relative supplies and wages of workers by education from 1940 to 1996 indicates strong and persistent growth in relative demand favoring college graduates. Rapid skill upgrading within detailed industries accounts for most of the growth in the relative demand for college workers, particularly since 1970. Analyses of four data sets indicate that the rate of skill upgrading has been greater in more computer-intensive industries.
